Aerosol generation

Abstract

Described herein is an aerosol generating assembly including a heater and an aerosolizable material, wherein the heater is arranged to heat the aerosolizable material in use, wherein the aerosolizable material includes at least two sections having different compositions.

The invention claimed is: 
     
       1. A method of generating an aerosol comprising:
 heating, in an aerosol generating assembly, an aerosol generating article comprising an aerosolizable material and a cooling element, wherein the aerosolizable material comprises a tobacco rod having a first section and a second section in abutting, adjacent relation, the first section having a first composition depleted in one or more volatile components relative to a second composition in the second section, wherein heating of the first section of aerosolizable material is initiated prior to heating of the second section, and wherein each of the first section and the second section contain tobacco. 
 
     
     
       2. The method according to  claim 1 , further comprising providing a different heat profile to each of the aerosolizable material first and second sections having different compositions. 
     
     
       3. The method according to  claim 1 , wherein the first and second sections are cylindrical and are arranged coaxially along the tobacco rod of aerosolizable material. 
     
     
       4. The method according to  claim 1 , wherein the composition in the first section of the aerosolizable material is depleted in one or more volatile components relative to the composition in a second section.
